The present study aimed at developing an analytical technique of audiovisual instructional materials in terms of iconic and verbal information processing. Fifty-three Japaneses and foreign educational TV programs were analyzed into auditory and visual components of different categories. The amount of information intended to convey by the sender was assumed to be proportional to the time length of presentation for each shot, so that a shot length measured in second is composed of auditory and visual presentation time components. A compound exponential model was introduced to approximate a variety of distributions of shot lengths of the video programs in terms of the two parameters alpha and beta respectively related to the auditory and visual presentation time components. The agreement between the therectical and the observed distributions for all the programs was very good. In order to explore the practical implications of the two parameters, qualitative as well as quantitative analysi … More s of shoes was carried out in terms of number of presenters, content of subject, relative amount of lecture presentation and "media complexities". All these findings were fairly conducive to the two component exponential model of audiovisual modalities. A multipicture display system which enables to present 16 partitioned pictures simultaneously was also developed to facilitate shot analytic technique and time sampling of pictures from video programs. Based on the two component exponential model, a theoretical formula for estimating the percentage of shots sampled by the time sampling with equal time intervals was derived and the formula found an excellent agreement between the expected and the observed values for all the programs. For most programs more than 95% of the shots were secured by the time sampling technique with less than 5 second intervals. Various applications of this multipicture presentation technique to the study of teaching-learning activities were discussed and attempted. Less

本研究旨在开发一种视听教学材料在图像和言语信息处理方面的分析技术。对 53 个日本和外国教育电视节目进行了不同类别的听觉和视觉成分分析。假设发送者要传达的信息量与每个镜头的呈现时间长度成正比，因此以秒为单位测量的镜头长度由听觉和视觉呈现时间分量组成。引入复合指数模型，根据分​​别与听觉和视觉呈现时间分量相关的两个参数α和β来近似视频节目的镜头长度的各种分布。所有程序的理论分布和观察到的分布之间的一致性非常好。为了探索这两个参数的实际影响，我们对演讲者数量、主题内容、演讲相对数量和“媒体复杂性”进行了定性和定量分析。所有这些发现都相当有利于视听模式的二分量指数模型。还开发了能够同时呈现 16 个分区图像的多图像显示系统，以促进视频节目中图像的镜头分析技术和时间采样。基于二分量指数模型，推导了估计等时间间隔时间采样的镜头采样百分比的理论公式，该公式发现所有程序的预期值和观测值之间非常吻合。对于大多数程序，超过 95% 的镜头是通过间隔小于 5 秒的时间采样技术获得的。讨论并尝试了这种多画面演示技术在教学活动研究中的各种应用。较少的
